Description

Technical Field

[0001] The utility model relates to the field of material conveying pipelines, in particular to a material conveying pipeline for coolant production. Background Art

[0002] The refrigerant is an intermediate cooling medium in an indirect cooling refrigeration device that transfers heat from the cooled system (object or space) to the refrigerant. Therefore, the refrigerant is also called the second refrigerant and is widely used in air-conditioning engineering, industrial production, scientific experiments and other fields.

[0003] During the production of refrigerant in related art, pipelines are required to transport raw materials, semi-finished refrigerant, or finished refrigerant. These pipelines typically include a material pipe with flanges at both ends, secured to the wall via multiple limit clamps.

[0004] However, the material pipes and limit clamps in the related technology are mostly made of metal materials, and there is a lack of buffering and shock-absorbing function between the limit clamps and the material pipes. When the material is transported through the material pipe, the material pipe will shake under the action of the fluid material and collide with the rigid limit clamp. Not only will there be loud noise, but there is also a risk of damage to the material pipe, which needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present utility model is to provide a material conveying pipeline for refrigerant production, which can achieve buffering and shock absorption between the limit clamp and the material pipe, thereby reducing the noise of the material conveying pipeline and the risk of damage and loosening of the material pipe.

[0009] The pressing plate is vertically slidably connected to the limiting hoop;

[0010] A control member is provided on the limiting hoop and is used to control the downward movement of the pressing plate so that the pressing plate is pressed against the material pipe;

[0011] The inner surface of the limiting hoop is provided with an elastic shock-absorbing strip, the bottom of the pressing plate is provided with an elastic shock-absorbing block, and the shock-absorbing strip and the shock-absorbing block can abut against the material pipe.

[0012] In a preferred example, the present invention can be further configured as follows: the shock-absorbing strip is semicircular, the shock-absorbing block can abut against the shock-absorbing strip, and a semicircular limiting notch is provided at the bottom of the shock-absorbing block for the material pipe to be inserted into.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the control element includes:

[0015] A receiving frame is arranged on the top of the limiting hoop;

[0016] A control rod is threadedly connected to the receiving frame, and the bottom of the control rod is rotatably connected to the pressing plate;

[0017] A control hand wheel is fixed on the top of the control rod.

[0018] In a preferred example, the present invention can be further configured as follows: the receiving frame and the limiting hoop are connected by fastening screws.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 、 Figure 2 A material conveying pipeline for coolant production includes a material pipe 1 and a plurality of limiting clamps 2. Each limiting clamp 2 includes a support frame 21, and the support frame 21 can be fixed to the wall by fastening bolts. A U-shaped limiting clamp 22 is fixedly connected to the side wall of the support frame 21, and the opening direction of the limiting clamp 22 is upward so that the material pipe 1 can be clamped into the limiting clamp 22. A clamping plate 23 is vertically slidably connected to the limiting clamp 22. At the same time, a control part 3 is provided on the limiting clamp 22. The control part 3 is used to control the downward movement of the clamping plate 23 so that the clamping plate 23 is pressed against the material pipe 1, thereby achieving the compression and fixation of the material pipe 1.

[0030] Reference Figure 1 、 Figure 2 The inner surface of the limiting hoop 22 is provided with an elastic shock-absorbing strip 4 in a semicircular shape, so that the material pipe 1 can be closely abutted against the shock-absorbing strip 4. The bottom of the pressing plate 23 is fixedly connected with an elastic shock-absorbing block 5, which can abut against the shock-absorbing strip 4. At the same time, the bottom of the shock-absorbing block 5 is provided with a semicircular limiting notch 6 for the material pipe 1 to be inserted into, so that the shock-absorbing block 5 can be closely abutted against the material pipe 1.

[0031] Through the elastic shock-absorbing strip 4 and the shock-absorbing block 5, buffering and shock-absorbing isolation is achieved between the material pipe 1 and the limiting hoop 22 and the clamping plate 23, so that the material pipe 1 and the limiting clamp 2 have a buffering and shock-absorbing function, avoiding rigid collision between the material pipe 1 and the limiting hoop 22 and the clamping plate 23 to prevent noise, and at the same time reduce the risk of damage to the material pipe 1.

[0032] In this embodiment, the shock absorbing strip 4 and the shock absorbing block 5 are respectively made of rubber, latex or silicone materials. Of course, in other embodiments, other elastic materials can also be used, which are not listed here in detail.

[0033] Reference Figure 1 、 Figure 2 The two sides of the clamping plate 23 are fixedly connected with guide blocks 7, and the inner walls on both sides of the limiting hoop 22 are respectively provided with guide grooves 8, and the two guide blocks 7 are respectively vertically slidably matched with the corresponding guide grooves 8, so that the clamping plate 23 can move vertically smoothly.

[0034] Reference Figure 1 、 Figure 2 The control member 3 comprises a support frame 31 mounted on top of the limiting clamp 22. A control rod 32 is bolted to the support frame 31. The bottom of the control rod 32 is rotatably connected to the pressure plate 23, and the top of the control rod 32 is fixedly connected to a control handwheel 33. Rotating the control handwheel 33 rotates the control rod 32, causing the pressure plate 23 to move vertically and clamp the material pipe 1. This design allows the limiting clamp 2 to adapt to material pipes 1 with different outer diameters, improving the adaptability of the limiting clamp 2.

[0035] Reference Figure 1 、 Figure 2 The receiving frame 31 is connected to the limiting hoop 22 by fastening screws 9, so that the receiving frame 31 can be disassembled, thereby enabling the material pipe 1 to be disassembled. In this embodiment, the receiving frame 31 is U-shaped and has an opening facing downward. Two fastening screws 9 are provided and located on both sides of the receiving frame 31.

[0036] Reference Figure 1 、 Figure 3 The material pipe 1 is provided with multiple silencing cavities 10 along its axial direction. These cavities 10 are evenly spaced around the circumference of the material pipe 1 and are each filled with a sound-absorbing cotton pad 11 to reduce noise from the material conveying pipeline. Furthermore, the outer surface of the material pipe 1 is wrapped with a cotton sound-absorbing layer 12, which not only further reduces noise from the material conveying pipeline but also improves the cushioning and shock-absorbing effect between the material pipe 1, the limiting hoop 22, and the pressure plate 23.
